算法设计与分析基础

前言

　　Algorithms play the central role in both the science and the practice ofcomputing. Recognition of this fact has led to the appearance of a con-siderable number of textbooks on the subject. By and large， they follow one oftwo alternatives in presenting algorithms One classifies algorithms accordingto a problem type. Such a book would have separate chapters on algorithms forsorting， searching， graphs， and so on. The advantage of this approach is that itallows an immediate comparison of， say， the efficiency of different algorithmsfor the same problem. The drawback of this approach is that it emphasizesproblem types at the expense of algorithm design techniques.　　The second alternative organizes the presentation around algorithm de-sign techniques. In this organization， algorithms from different areas of com-puting are grouped together if they have the same design approach. I sharethe belief of many （e.g.， [BAY95]） that this organization is more appropri-ate for the basic course on the design and analysis of algorithms. There arethree principal reasons for emphasis on algorithm design techniques First，these techniques provide a student with tools for designing algorithms for newproblems. This makes learning algorithm design technique a very valuableendeavor from the practical standpoint. Second， they seek to classify multi-tudes of known algorithms according to an underlying design idea. Learn-ing to see such commonality among algorithms from different applicationareas should be a major goal of computer science education.
